This closely resembles the bucking coil jumpering.
For those of you that have coils already, they are similar besides the wire and turn specs, just fire it up. The collectors are only used for output. They are not connected to the input side of the circuit. Be careful of the voltage and sparks.
And by all means put things in the center. It moves magnets, water, it heats steel, vibrates, jerks motors, it goes bump in the night.
Any volume of copper and diameter seem to work. It do 7.8hz!
Vary the hall effect distance to tune. If anyone can replace the halls with something else then by all means go ahead.

Control coils: 72 turn each 32"(?) 4"
26 gauge phone wire

yes 1. Assume first wires to go on cylinder ring form? 1" length of PVC pipe. Makes easy winding. Wind it on (bunched up is fine. doesn't have to lay flat) then cut pipe to length.
yes 2. Typo: should be 32'4", (32 feet 4 inches,) not 32"4", right?
yes 3. Phone cord; you mean the four-wire stuff?
No feedback coil in circuit yet. That could be the way to alleviate the Hall effect tranny.

Collector Coil (secondary) 70 turns, 51'
3(?) gauge mag-wire

No 1. Final wrap over four control coils? No final or feedback.
yes 2. Typo: we mean 30 gauge mag-wire, right?
yes 3. Wrap in RHR fashion, going clockwise around? This matches the original GK4 spec.
yes 4. (Forgot to ask same question for Step Two,) RHR-clockwise direction for control coils as well; ugh,... may I wrap all winds in the same sense?

If you already have a 4 segment wired just try this. If it is not right then wind a new one.
I am winding the GK4 twin. I want 2.

@joe dirt,
you feel like upgrading your GK43 pic?

I am but a mere messenger for the cause.
Sorry guys. No time for the bull-shit. Just 'Git 'r' dun!'.

Hi Ya JD:
   Did your circ but added one more pair to make three. Due to the low resistance I started it out on 3v and it puts out 30. Oscilations are running around 1.7 mhz on mine. Its very interesting but amp hungry. Easily tries for one amp at 7.5v. Will be messing with it more as I get the time. 4 work days ahead and I get little time in between to do anything but work,eat and sleep. Good design. Mine started to osc as I wired up the last trigger wire to the center of the two resistors. They go no where right now and it still goes. That may mean a bad tranny but will see. Going to hook up  a diode and cap on the outside coil and join it back into the power to see if it will leach on its self. More to come.

I conducted a patent search on Applied Materials Inc (patent assignee of Steve's device) and came across thousands of patents. After filtering with keywords there was one that stuck out of all the results.

Can someone here be kind enough to take a look and find any insight? Some users here have reported success with 3 frequencies. The T.P.U controller/methods might be disclosed in this patent's descriptions.

Use of variable RF generator to control coil voltage distribution #6,345,588

"an RF generator coupled to said impedance matching circuit, said generator generating an RF signal having a cyclically variable frequency which shifts between at least three frequencies in each cycle for time-averaging voltage distributions along said coil. "
